INSTALLATION

THE LAW REQUIRES THAT INSTALLATION IS CARRIED OUT BY A PROPERLY QUALIFIED PERSON
Install in accordance with current British Standard Code of Practice 342 part 2 and British
Standards 5440, 5546, 6644, 6700, 6798 and 6891.
The location chosen for the heater must permit the provision of a satisfactory flue and an
adequate air supply.
A clearance of 3OOmm (l2in) should be left around the heater for fitting and servicing
purposes and 762mm (3Oin) above the heater for removal of the flue baffle. The above
clearances are recommended for ease of servicing. They can be reduced if necessary but a
clearance of 3OOmm (12 in) must be left in front of heater for access to the burner and
controls. The flue baffle clearance should also be maintained if possible to avoid servicing
problems.
The floor on which the heater is installed must be flat, level and of sufficient strength to
withstand the weight of the heater when filled with water, and should satisfy the
requirements of the Local Authority & Building Regulations.
Any combustible material adjacent to the heater must be so placed or shielded as to ensure
that its temperature does not exceed 66°C (150°F).
Detailed recommendations for flueing are given in British Gas Booklet IM/11 and
BS 5440 part 1. The following notes are intended to give general guidance:
• A horizontal or vertical flue kit is supplied with each heater. Flue fitting instructions on
page 6.
• Location. The siting of the flue terminal is not critical with respect to the performance of
the unit. However, areas where the discharge of combustion products would cause a
nuisance should be avoided. In accessible positions a suitable guard should be provided.
(see page 6).
• Route. The route of the flue is not critical, with three installation options available. See
below for permissible flue lengths. Where installation options 2 or 3 are used we
recommend that the flue outlet can be installed in any configuration through 180º as
long as proper service clearances are observed see fig.1 page 4.
